Storage ideas for chess pieces and board:
The chess board is 17*17 (non-standard, decided by a stroke of the head at that time). Generally speaking, it is very brain-friendly to store the information of the chess board with a two-dimensional array chesses[17][17]. However, the two-dimensional array is inconvenient to store directly with chesses[17 * 17]. It is also well understood that the array index corresponds to each chess X + Y * 17 (You may need to understand this), or the coordinates inverted by the index are: X = i (array index)%17; Y = i / 17;.
chesses[17 * 17] is the data stored on the board. The next chess piece will create a new chess object at the corresponding index and draw an image of the chess piece at the corresponding coordinates.
Falls are stored in TreeMap, key s in the order of falls (1,2,3,4...), and value s in the one-dimensional array index of the pieces.
The advantage of this storage is that it is easy to read the data and read the archive.
Of course, there is another way of thinking:
Because the order OrderNum is declared in the Chess class, it is also convenient to use ArrayList to store the drop information and the board information directly.
Chess pieces:
//If the game is over, canPlay = false
if(canPlay) {
//Chess pieces
int x = (e.getX() - 60) / 40;
int y = (e.getY() - 60) / 40;
if (e.getX() >= 80 && e.getY() >= 80 && e.getX() <= 720 && e.getY() <= 720) {
//Fill
if(chesses[x + y * 17] == null) {
chesses[x + y * 17] = new Chess(x,y,countNum++,isBlack);
isBlack = !isBlack;
isSaved = false;
//Test: Number of chess pieces + abscissa + ordinate
System.out.println(chesses[x + y * 17].getOrderNum() + "..." +chesses[x + y * 17].getX() + "..." + chesses[x + y * 17].getY());
//test
System.out.println(maxLine(chesses[x + y * 17]));
}
tm.put(chesses[x + y * 17].getOrderNum(), x + y * 17);
this.repaint();
}else {
return;
}
//Judging the winner or loser
isWin(maxLine(chesses[x + y * 17]));
}The maxLine method:
In meter shape judgment, the longest number of concatenates in the oblique direction from top to bottom is determined each time a faller falls.
The basic idea: Take the horizontal as an example, to judge the longest conjoints with index (+) 4 after falling a piece, we need to pay attention to one problem, that is, the pieces are on the boundary of the board, we need to add a judgment. If the vertical coordinates change (to another row), the maxLine is recalculated. If it is a vertical judgment, the X coordinates need to be monitored for change; if it is oblique, the Y coordinates need to be monitored, and if it changes to 2, the maxLine is recalculated.
//Judging the Longest Connector Number
public int maxLine(Chess chess) {
int xLine = 1;
int yLine = 1;
int rightLine = 1;
int leftLine = 1;
int max = 1;
int index = chess.getX() + chess.getY() * 17;
//Horizontal Judgment

}canPlay is used to control whether or not you can play chess. After a game has won or lost, you can't continue falling. You need to repent or start again before you can continue.
This achieves the basic function of chess. As for restart, repentance and other functions, it is easy to achieve them in the single-machine version, then the code will be po oled out, first a slightly more complex reading function:
First look at the effect map:
When you have selected the document, (Save one without saving the document) The three function keys "Previous Step", "Load Game", "Next Step", "Previous Step" and "Next Step" pop up It is used to read the files, to know the order of the falls, and to pick the desired progress to start the game. Click Load to start a game from the board in the current picture. Then, the three function keys disappear until the progress is read again.
The drawing implementation code of the function key is in the drawing, and the function implementation code is as follows:
if(e.getX() >= 770 && e.getX() <= 870 && e.getY() >= 380 && e.getY() <= 420) {//Here are the coordinates
int isYes = JOptionPane.showConfirmDialog(this, "Whether to read progress","readload",JOptionPane.YES_NO_OPTION);

}
//test
System.out.println(tm+" " + SIZE + "\n" +tmTemp + count );
}
if(count == SIZE) {
downCanPress = false;
}else if(count == 0) {
upCanPress = false;
}else {
downCanPress = true;
upCanPress = true;
}
this.repaint();
}readLoad method:
//Read function, pop-up window selection to save documents
public void readLoad() {
JFileChooser chooser = new JFileChooser();
FileNameExtensionFilter filter = new FileNameExtensionFilter("(*.txt)", "txt");
chooser.setFileFilter(filter);
int option = chooser.showOpenDialog(null);
if(option==JFileChooser.APPROVE_OPTION){
File file = chooser.getSelectedFile();
System.out.println(file.getAbsolutePath());
restart();//Defined method of reopening: board empty, archive empty...
try {
br = new BufferedReader(new FileReader(file));
String line = null;
while((line = br.readLine()) != null) {
String[] arr = line.split(" ");
int num = Integer.parseInt(arr[1]);
if(chesses[num] == null) {
chesses[num] = new Chess(num % 17,num / 17,countNum++,isBlack);
isBlack = !isBlack;
tm.put(countNum - 1, num);
this.repaint();
isWin(maxLine(chesses[num]));
}else {
JOptionPane.showMessageDialog(this, "File read error\r\n Chess repeat");
break;

}
}Involves the use of classes for IO streams and pop-ups, and how to archive can be modified to suit your own development needs.
When reading an archive, because there may be more than one Previous Step and Next Step, here you choose to create a new TreeMap to copy the archive. The purpose of this TreeMap is to save the complete archive file. The next step is to implement the new TreeMap created before us to archive the file. This ensures repeating the previous and next steps.
When you click Load Game, copy the temporary TreeMap into the TreeMap where the data is stored on the board.
A judgment will be made when the previous or next step is not possible. The keys that will not be executed (for example, when you start reading the file, you cannot click Next Step, or when there are no pieces on the board, you cannot click Back Step) In the drawing code block, just change the last value of the key method to false. The canPress Boolean variable is defined to do this.
Here is the implementation code for the other functions, and again, the implementation of the drawing is in the top block of code.

}This basic single-machine version is complete. Because the code is cut from the full version, it's messy, but that's okay, there's a summary of all the code at the end.
Another difficult feature to achieve is networking. (After half a month of overnight to achieve this function, of course, it is not difficult to recall now, I have not done well in my own foundation.)
There are many ideas for networking. You can set up a server class. The code of the board class only needs to complete the socket to connect to the server. Of course, the server construction will take a lot of effort. After all, there is matching (opening a room) and prohibiting others from joining these functions needs to be considered.
I chose another simple idea: Checkerboard inherits the Runnable class, overrides the run method, and when I click on the networking function key, opens a thread in which a ServerSocket receives information from another client.
When you need to send information, call the send method and create a new socket to connect to the other server to complete the information interaction.
There is also a mouthful to add here. The information of a falling piece is very understandable: When a falling piece is dropped, just give the index of my falling piece in the chesses[] array to the other side, then what about the function keys?
I choose to use constants instead. Checkerboard pieces only need a range of 0 to 17*17 - 1. Starting with 17*17, they can be defined as information for function keys. Specific code:
@Override
public void run() {
// TODO Auto-generated method stub
System.out.println("implement run()");
String line = null;
try {
server = new ServerSocket(Integer.parseInt(yourPort));
while(true) {

}Three methods are used to implement [Open Server] [Send Information] and [Translate Information].
After that, we only need to make some adjustments on the single-machine version. Each time we make changes to the chess board, we pass the corresponding information to the other side, which is translated by the translator() method and then make corresponding actions on the board.
All the code is here:
This is the main chessboard class, where almost all functions are implemented (arguably not):

}Finally, give an effect picture:
This is the first page, with one computer on the left and networking on the right. In the upper right corner is the background music. Click to pause while the picture changes.
Single machine is the cover page, another networked:
Once you have finished typing, you can start the game. (LAN)
No Click to start online, the small window is not closed, and the board is not operational.
Code source files and used picture music have been uploaded to the cloud, you need to take your own:

Of course, there must also be some little buddies who do the work of Gobang, in addition to the specific IO balloon window drawing class, try to see after their own hands.
